(05-12) 10:41 PDT OAKLAND -- Authorities have now identified both of the people killed in a single-car crash in Oakland that seriously injured three others Sunday.

The Alameda County coroner said Kenisha Lewis, 28, and Duwan Palmer, 21, died when a vehicle with five people inside smashed through a chain-link fence before crashing into trees at Seminary and Outlook avenues near the Mills College campus.

The car was badly mangled, with four people trapped inside. The fifth person was found a short distance away near 55th Avenue and MacArthur Boulevard, but it was not clear how that person got there, said Battalion Chief Emon Usher of the Oakland Fire Department.

Emergency crews used hydraulic equipment to pull the trapped victims from the wreckage. Three were taken to Eden Medical Center in Castro Valley, and two were transported to Highland Hospital in Oakland, Usher said.

The conditions of the three other victims were not available Monday. The Oakland Police Department's traffic division is investigating the cause of the crash.
